The princes of Qi joined forces with 300,000 troops and marched south. After capturing Pi, the Huai army could not hold out.

Coalition battalion.

"Ladies and gentlemen, now that the coalition forces have captured Pi Banyue, but they have worked in vain, and the soldiers are dead and wounded, what good strategies do you have to break through? If you succeed, you will be rewarded!"

"Alliance leader, the Huai army has the city wall to rely on, the archers are condescending, our army shoots from the back, it is not the opponent of the Huai army, it cannot suppress the Huai army on the city wall, let the army attack the city and force the attack, our army has suffered heavy casualties." Zheng Guo's secretary of state said.

Everyone agreed, saying that the Huai people had sharp bows and crossbows, and the attack suffered heavy casualties.

"Alliance leader, the Huai army has a sharp bow and crossbow, but it is condescending and has a geographical advantage, it is better to let the people build a platform outside the city of Xiapi, so as to be higher than the city wall, and let the archers shoot arrows at a high altitude to suppress the Huai people." Qi Guoqing Shi Yan explained.

"Yan Qing's strategy, what do you think?" Qi Hou asked left and right.

"I think Dr. Yan's strategy is feasible!" Zheng Hou next to him said directly.

"Alliance leader, I feel that it takes a long time to build a platform, and I am afraid that the Huai people in the city will go out of the city and destroy it." Cao Hou said.

"If you send two armies to guard the left and right, if the Huai people sneak attack, the two armies will attack together, or you can take advantage of the situation to seize the city." Wang Chengfu said.

"Then let's go ahead with this good plan! The people of the expedition are strong in the outer city of Xiapi to build a city, Wang Qing led the two armies to ambush on the left and right, if the Huai people really dare to come out, the two armies will go together to seize the city gate!" Qi Hou ordered directly.

After the order was issued, the army immediately began to fight, and tens of thousands of people were dragged to build a city outside Xiapi City.

The defender of Xiapi City saw that the Qi army was no longer attacking the city today, but was building soil outside the city, which was very strange, and hurriedly reported it.

"Wei Qing, the alliance of the princes built a platform outside the city, thinking that they wanted to make the archers condescending to suppress the archers on the city wall, these Qi people are really fast to learn!" Wang Sheng frowned slightly.

Wei Jun said: "Your Majesty, the princes of Qi are many powerful people, if they really succeed in building the platform, they will be condescending at that time, but they will be able to suppress the archers of our army's city head, and the morale of the army is unfavorable, so please go to war and lead the army to destroy it!"

"Your Majesty, the princes of Qi are full of troops, and it takes a long time to build a platform with soil, how can they not guard against a surprise attack by our army, if your subordinates expect it to be good, the Qi army must have ambushes on both sides, and if our army sneaks up, it will just fall into its trap." Ram Shuo hurriedly stepped forward and said.

"What Ram Qing said is good, I am afraid that I will not be able to destroy that high platform if I go to war rashly, and our army will also suffer heavy casualties." Wang Sheng nodded.

"Why not strike at night?" Wei Jun said.

The most elite soldiers of Huai State, whether they are the Tengjia Army or the Yulin Army, are all professional soldiers, with sufficient supplies, no night blindness, and proficient in night warfare.

"Then try it." Wang Sheng thought for a while and agreed.

Two days later, the 3,000 elite of the Huai army attacked the mound outside the city at night, and the defenders of the Qi State were unprepared, suffering heavy casualties, and the mound was destroyed overnight.

In the camp of the coalition army, Wang Cheng's father pleaded guilty to the Marquis of Qi. Instead of blaming, Qi Hou comforted: "Victory or defeat is a common thing in soldiers, Wang Qing doesn't have to mind, this battle Huai destroyed the mound, obviously knows the threat of this mound, Qing will rebuild the mound, if the Huai people come again, can you have the confidence to win?"

"Don't worry, if the Huai people come again, the minister will definitely let them come back!" Wang Chengfu said loudly.

Wang Sheng was very happy to learn that the night attack was successful, not only destroying the mound, but also killing 2,000 Qi troops. But the next day, the Qi army built a mound outside the city again, and the original happy mood was like eating a cockroach.

"Your Majesty, why don't you go to the night attack at night?" A doctor next to him said.

Wang Sheng shook his head and said, "The night attack is originally about suddenness, since it has been used once, the Qi army will definitely be on guard, and it will not work if you want to sneak attack again!"

"Shall they be allowed to build a platform there?"

"The minister remembered that he had read King Wen's book "Armament", which had the method of attacking and defending, and the enemy built a mound of earth, which could be covered with wooden planks at the head of the city!" Ram Shuo Road.

"Order the craftsmen to make planks and cover them over the walls! It's up to the Ram Qing to take care of it!" Wang Sheng thought for a moment and said directly.

"Will I be ordained!" Ram Shuo said directly.

Wang Sheng had also thought about using the Heavenly Mandate Artifact to summon Heavenly Fire to descend into the world and attack the Qi army. However, after looking at the cost of using it, he gave up on the idea for the time being.

First of all, the Heavenly Fire Card Artifact summons a limited number of Heavenly Fire, at most destroying a few nearby camps, and there are dozens of coalition camps, stretching for miles, a Heavenly Fire Card can't solve the problem at all, and using the Heavenly Fire Card will have to bear the power of the artifact's backlash, in addition to consuming Qi luck, he himself needs to live for five years.

For the princes, no one will use this way unless it is absolutely necessary.

The State of Qi built the city again, and the State of Huai did not send people to attack again, which made the State of Qi a little puzzled, but after no interference, soon a platform higher than the city wall of Xiapi was built. Immediately, the Marquis of Qi again ordered the army to attack the city.

The earthen platform was full of archers, and when the army attacked the city, these archers immediately threw at the head of the city to suppress the Huai army at the head of the city.

But just as the archers were throwing, a roof-like wooden sign suddenly rose on the head of Xiapi City, covering the entire city.

'Knock knock... The continuous sound of percussion sounded, and I saw the arrows thrown by the allied archers falling from the sky, just blocked by all the wooden signs.

The earthen wall built by the Qi State with a lot of manpower and material resources did not play a role in the slightest.

Seeing that the rain of arrows from Qi was blocked, the archers of Huai immediately stepped forward and shot a rain of arrows at the soldiers who were carrying cloud ladders to attack the city, and the soldiers of the coalition army fell in pieces like cutting wheat.

Even if some soldiers barely climbed the city wall, they would be rushed up and killed by the soldiers who had been guarding the city for a long time. Rolling logs and rocks fell, arrows rained down, and the coalition forces suffered heavy losses in the siege, and soon the army had to retreat in disarray.

In the camp of the coalition army, Qi Hou's face was ugly. Spending so much time building a platform not only did not serve any use, but on the contrary, it lost troops and reduced its prestige.

Among the coalition troops, there were also ministers who offered advice and dug tunnels, hoping to enter the city and cooperate inside and outside to capture the city. The coalition army immediately adopted it, but the Huai army had already prepared, laid urns in the city, sent soldiers to listen, and then dug trenches in advance. After the coalition soldiers dug up the tunnel, they immediately shot with bows and arrows, and threw in firewood to smoke the coalition soldiers in the passage.

The coalition forces besieged Pi for a month, and used various siege methods, all of which were resolved by the Huai army one by one. The two sides can be said to have shown their magical powers, and various siege methods were used, and then they were cracked by the Huai army one by one.

It can be said that in the past month or so, the war between the allied forces of the princes of Qi and the Huai State has demonstrated almost all the siege tactics. The allied forces of the princes of Qi were menacing, but they could not advance, and Huai had no way to win, and the two sides were in a stalemate.
